Abstract
A method to form an electrical component, comprising: overlaying a conductive and adhesive layer on a body and covering a first portion of a terminal part of a conductive element, wherein a second portion of the terminal part of the conductive element is not covered by the conductive and adhesive layer; and overlaying at least one metal layer on the conductive and adhesive layer and covering the second portion of the terminal part of the conductive element, wherein the at least one metal layer is electrically connected to the second portion of the terminal part of the conductive element for electrically connecting with an external circuit.
Claims19
A method to form an electrical component, comprising:
- providing a body, wherein a conductive element is disposed in the body, wherein a terminal part of the conductive element is exposed outside of the body with said terminal part exposed outside of the body being entirely disposed on a bottom surface of the body;
- overlaying a conductive and adhesive layer on the body and covering a first portion of the terminal part of the conductive element, wherein a second portion of the terminal part of the conductive element is not covered by the conductive and adhesive layer;
- and
- overlaying at least one metal layer on the conductive and adhesive layer and covering the second portion of the terminal part of the conductive element with a portion of the conductive and adhesive layer being located between the at least one metal layer and the first portion of the terminal part of the conductive element and in contact with the at least one metal layer and the first portion of the terminal part of the conductive element, wherein the at least one metal layer is in contact with and electrically connected to the second portion of the terminal part disposed on the bottom surface of the body for electrically connecting with an external circuit.
